The Lowdown
Alright, Rusty here, let's look at what Karramarro has cookin' over the next couple of weeks.
First up, the water is way warmer than usual – running about 25°, which is a solid 3° above what's normal for this time of year. Feels like a warm bath out there.
Right now, Wednesday the 26th and Thursday the 27th are flat as a pancake. Tiny 1ft to 3ft waves with barely any energy (42 to 101). The wind is glassy, but there's nothing to ride. Thursday afternoon gets a little bump in energy but still nothing worth paddling out for.
Friday the 28th morning finally shows some life. Clean 5ft swell from the WNW, period of 8 seconds, with light offshore winds. It's surfable but just average – nothing special. That afternoon the wind turns onshore and the waves hit 6ft, but it gets messy.
Saturday the 29th morning – now we're talking. Glassy conditions, 5ft of NW swell, period of 9 seconds. The energy jumps to 418 (moderate). This is the first real standout. Clean, glassy, with enough push for some fun waves. Crowds are *often* around here, so bring your patience, but the quality should be good.
Sunday the 30th morning is another solid option. More glassy conditions, 5ft from the NW, period of 9 seconds, energy at 275. Nice follow-up to Saturday morning. But by the afternoon the wind goes cross-on and the quality drops.
Monday the 31st through to Thursday the 3rd of September is a flat, messy stretch. Swell holds around 4ft to 6ft but the wind stays cross-on or onshore. Marginal at best.
Friday the 4th is small again – 2ft, clean but weak – and Saturday the 5th isn't much better.
But here's the one – Tuesday the 8th of September morning. Dead calm, glassy, 5ft swell from the NW, period of 10 seconds, energy at 460 (moderate). That's a proper session. Zero wind – glass offshore. This is the standout of the whole 16-day window. It's a week and a half away so don't book your flights yet, but if it holds, that morning will be the best of the lot.
Wednesday the 9th morning is okay – 3ft, glassy, but much smaller. Then we fade back into tiny waves through the 10th.
So to sum it up: best windows are Saturday 29th and Sunday 30th mornings, and the long-range one to watch is Tuesday 8th September morning. The rest is mostly flat or ordinary. Don't waste your time on the middle week.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
